It may come as some unwelcome news to the families of the nearly 60,000 Americans who died in the Vietnam War that the whole thing was just a misunderstanding.

That was the impression President Obama gave on Thursday when he spoke to the press after his meeting with Vietnamese President Truong Tan Sang. Sang brought Obama a copy of a letter sent to President Harry Truman from Ho Chi Minh in which the communist dictator spoke hopefully of cooperation with the United States.

Obama, striking a wistful tone, observed that it may have taken 67 years, but the United States and Vietnam were finally enjoying the relationship that Ho once wrote of. After all, Obama said, Ho had been “inspired by the words of Thomas Jefferson.”
